The thesis is part of IBCleaning and Robotdalen project "Automated Ice-blasting" are based on blasting walls on the inside of cargo containers with dry ice using an industrial robot and therefore clean the surface. To insert the industrial robot in the dirty container a specially designed rail system has been developed.This thesis aims to analyze and calculate the strength parameters of the assembly consisting of the robot and the specially designed rail system. One more task is to examine whether there is an opportunity to contribute to an improvement proposal. The report describes briefly Ice Blasting and how the automation of this can be designed. Literature Studies in solid mechanics and tutoring in ANSYS has been performed in parallel with the work and used to compare, evaluate and resolve the various situations that occur in the construction. FEM analysis using “ANSYS program” has been implemented to support the calculations and analysis realized. ANSYS was also used when it was not possible to perform a manual calculation due to the complicated procedures or multiple operations simultaneously.I spent some of the time to realize 3D-drawings using ”Pro-Engineer program”, drawings that have been sent on to ANSYS to perform various tests on the design and obtain concrete results.The calculations are performed based partly on information from the company and partly on reasonable assumptions in order to supplement missing data in the spreadsheet calculations.
